1. Roof ventilator is a kind of ventilation facility installed on the roof of a building, and it is also a device or equipment used to enhance air circulation.
2. There are many kinds of roof ventilators, which are mainly divided into natural ventilators and external power ventilators according to their working principles.
3. Roof ventilator, as a mainstream ventilator, is widely used in various public buildings and steel structure workshops, with no power consumption and convenient maintenance.
4. According to the shape characteristics and ventilation volume, it can be divided into spherical ventilators and strip ventilators. Its work is based on the characteristics of upward gathering of hot air and the principle of fluid thermodynamics. With the difference in indoor and outdoor air pressure and temperature, supplemented by natural air, the ventilators can automatically operate under natural conditions to maintain natural ventilation.
